N. PETERS, FHOTO-U UNrrnn "ra'rns GEORGE WV. PRESSEY, OF HAMMONTON, NEW JERSEY, ASSIGNOR OF ONE- HALF HIS RIGHT TO EDWIN L. (JROWELL, OF SAME PLACE.

SCYTHE AND OTHER BLADE FASTENING.

SPECIFICATIONfor-ming part of Letters Patent No. 234,721, dated November 23, 1880.

Application filed July 13, 1880.

To all whom it may concern:

Be it known that I, GEORGE W. PRESSEY, a citizen of the United States. residing at Hammonton, in the county of Atlantic, State of New Jersey, have invented a new and useful Improvement in Scythe and other Blade Fastenings, which improvement is fully set forth in the following specification and accom panying drawings, in which- Figure 1 is a front or face view of the fastening embodying my invention. Fig. 2 is a section thereof in line m m, Fig. 1. Fig. 3 is a perspective view of a portion thereof.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists in forming a blade with a segmental end, which, when fitted to the handle, provides means of adjusting the blade or setting it at different angles.

It also consists of fastenings of wedging form for securing the blade to the handle.

Referring to the drawings, A represents a scythe or blade, and B the snath or handle thereof.

0 represents a face-plate, which is screwed, riveted, or otherwise firmly secured to the upper or blade end of the handle, and has form ed with or connected to its outer edge lugs D D, of which the lug D is of somewhat hook form and the lug D is pointed or toothed.

E represents a bolt, which is passed freely through an opening in the handle B, and its head a is tapering or wedging and projects beyond the face-plate. The threaded end of the bolt has fitted to it a thumb or other nut, E, which tightens against the handle B, and between the nut and handle may be placed a washer for well-known purposes.

The end A of the blade to be attached to 4.0 the handle is a segment or of segmental form, and the location of and the distance between the lugs D D and head a of the bolt E are such that the segment may be readily passed into the space between said lugs and bolt-head 5 by a lateral motion.

On the back of the segment A is a series of notches or teeth, b, with which the toothed lug D is adapted to engage, and the edges of the segment which are to come in contact (No model.)

with the lug D and head a are beveled, as at a a, to accord with the shape of said lug and head.

The operation is as follows: The bolt E is loosened and the segment A inserted between the lugs D D and head a of the bolt, it being noticed that one of the notches b is in engaging contact with the toothed lug D. The bolt E is now tightened, and its head a, wedging against the beveled edge of the segment, forces the segment against the lugs D D, and thus the blade is most firmly and reliably fastened to the handle, the lugsD D and bolt preventing displacement of the blade up or down in the direction of the length of the handle, and the lug D preventing lateral displacement.

In order to adjust, set, or hang the blade, the bolt E is loosened to allow play of the segment A between said bolt and the fasteninglugs. The segment is then moved in or out between said parts D D E until the adjustment is accomplished, the proper tooth of the series 12 then engaging with the lug D. The bolt E is again tightened,and thus the blade and handle are securely connected, as before.

It will be noticed that, owing to the curvature of the segment and its relation to the fastening-lugs and bolt, it does not change the direction of rotation as it is moved in or out between said fastening-lugs and bolt; but the blade, following the movement of the segment, is caused to change its angle of direction from the handle, and thus means are provided for adjusting the set of the blade relatively to requirements.

In order to firmly secure the face-plate O to the handle and adaptit to handles of different thicknesses, I form on diagonal corners thereof ears F, which may be bent out or in to enlarge or reduce the space between them for the requirements of the case.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The scythe-blade A, having a segmental rear end, A, which is provided with a series of notches, b, on one of its curved edges, and has both curved edges beveled, as at a a, substantially as set forth.
